This, I think, is the issue...natural resins. Moisture can be put
back in wood, the natural resins cannot (I think). I believe the
natural resins are what permits the wood to flex but not break.

I have had mold in the shop...moisture is there. <g> It is
within 30' of the edge of a south Mississippi swamp and was not always
air-conditioned or heated.

You think? Go grab some of it and bend it and treat it like you used
to and see if the sheets split and the sticks become three or four
shorter ones when waved figorusly around the room.

Basements down here would be an indoor pool.

I have arranged a little test. I really hate the idea of throwing out
over $700 in balsa.

I have replaced old balsa. It was brittle. It may have been brittle 20
years ago but it wasn't going into a plane I was building.

I know I can use it for other stuff (?) but most of the time we want
the lightness and strength...I guess if I was into HO trains, there
would be other things I could do with it.
